It appears Apple left one item out of its Worldwide Developers Conference (WWDC) yesterday: its Tile-like tracking device. Earlier this spring, we learned that Apple is supposedly working on a tracking tag, but the company didn't mention it amidst news of its updated operating systems, Mac Pro and HomeKit security improvements. However, in the iOS 13 beta, developers spotted an asset package for a device with the product type "Tag1,1." As 9to5Mac reports, that type of asset package is used for pairing devices by proximity -- like AirPods and HomePod. It's more evidence to support rumors that Apple is working on a tracking device.
